摘要:
A photoelastic and strain gauge analysis was performed to evaluate the stress transferred to implants through the provisionalcement-retained, the permanentcement-retained, and the screwretained prostheses. The deflections of the prostheses at the time of the loading were also measured. In the single crown test, the provisionalcement-retained crowns transferred less stress. In the two-unit fixed partial denture test, there were no differences between the three different prostheses. In the two-implant supported distal cantilevered prostheses, the screw-type and the permanent-cement-retained prostheses developed more stress around the apex of both implants. The permanent-cement-retained prostheses acted almost the same as the screw-type.
